Cross-section through the middle of the penis. (Dorsal artery visible at top.)

The Dorsal artery of the penis is a branch of the internal pudendal artery which ascends between the corpora cavernosa penis and the tunica albuginea, supplying blood to the penis.

Structure

The dorsal artery of the penis is one of the three arteries of the penis, the other two being the deep artery of the penis and the artery of the bulb of the penis. It arises from the internal pudendal artery and travels along the top of the penis, between the corpora cavernosa. It gives off several smaller branches which supply the urethra, the skin of the penis, and the prepuce.

Function

The dorsal artery of the penis is responsible for supplying blood to the skin, prepuce, and corpora cavernosa of the penis. It plays a crucial role in erection and sexual arousal.

Clinical significance

Problems with the dorsal artery of the penis can lead to erectile dysfunction. This can be due to atherosclerosis, where the artery becomes blocked with fatty deposits, or due to injury or surgery.
